Resist pattern defined by inwardly arched lines
View Patent ↗A device pattern of a semiconductor device. The pattern is defined by a plurality of non-straight lines that are inwardly arched and are formed from plural segments of plural ellipses that are arranged to surround the pattern.
1. A resist pattern having at least a pattern which is defined by non-straight lines,
wherein said pattern is defined by plural points and inwardly arched lines connecting said plural points so that said pattern has a plurality of tapered corners,
wherein said inwardly arched-lines comprise six corners and six segments connecting said six corners, where said six segments are of six ellipses arranged to surround said pattern, where adjacent two of said six ellipses are in contact with or partially overlapped with each other.
2. The resist pattern as claimed in claim 1 , wherein said pattern is for forming a storage electrode of a capacitor of a semiconductor device.
3. A resist pattern defined only by plural points and inwardly arched lines connecting said plural points so that said pattern has a plurality of tapered corners.
4. A resist pattern defined by plural points and inwardly arched lines connecting said plural points, wherein said inwardly arched lines comprise plural segments of plural ellipses arranged to surround said pattern.
5. The resist pattern as claimed in claim 4 , wherein an adjacent two of said plural ellipses are in contact with or partially overlapped with each other.
